ELECTRIC GENERATOR.

T o all whom it may concern:

Be it known that I, JOSEPH .BELL, a c1t1- zen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Electric Generators, of which the following is aspecification.

My invention relates to improvements in that type of electric generators where the armature rotates in one direction and the field 'in the other; and consists in anew and useful combination of parts, forming a cal both in the expenditureof power, cost of construction and of maintenance, besides possessing the advantages of reduced space and weight. Should either of the motor connections become disabled, the pitmen may be-removed and that rotating element secured against rotation and the dynamo kept in operation for the time being thus securing operation at the efiiciency of an ordinary generator instead of shutting down I "the dynamo altogether.

My invention is illustratedin the accompanying drawings in which- Figure 1 is a top plan view of a dynamo whose elements rotate in opposite directions and a single-cylinder reciprocating engine and pitman connections for operating said dynamo; Fig. 2 is an end elevation of the frame, showing thearmature and field'cases in section, the driving mechanism being omittedl Referring now to .the drawings, A is a crank-shaft journaled on the pillow blocks e, e with an armature casing a fixed to the inner end of said shaft. This casing a is made heavy on the rim (4 to act as a flywheel, and is shown in the drawing with its spokes bent inwardly so as to economize space and bring the cranka closer to the Specification of Letters Patent.-

casing. The casing a carries the armature laminations a and electrical connections.

The crank shaft F which has a crank 1s journaled in the axial line extended of shaft A on the pillow blocks 6 6 with a field casing f 'fixed to the inner end of said shaft, and a rim f all similar in all respects to the casing and its accessories upon the shaft A. The cores 7' are built up in the caslng f. A pitman c connects the crank f,

and a pitman e connects the crank it with opposite ends of a wristpin (2 through the cross-head 6 operating in the usual guides. This cross-head is attached to the pistonrod e ofthe single cylinder engine E.

The arrows on the casings (Hand 7 indicate that they are intended to be rotated simultaneously in opposite directions and with the connections shown in Fig. 1 this maybe effected by the same reciprocating source of power. Withsuch connections in starting the engine one crank should be up and the other down, so that the initial impulse will drive the shafts A and F in opposite directions, which relation is maintained through theaction of the rotating field and armature ca sings operating as regulating fly-, wheels, each in relation to its shaft. Y

I claim as my invention and desire to secure by Letters Patent of the United States.

1. An electrical machine embodying two non-contacting crank shafts mounted to ro- I tate in,a common axial line extended; an armature carried by one of said shafts, and a corresponding field element by the other in operative relations each with the other; pitmen connected at one end with the cranks of said crank shafts respectively, and at the other with a common reciprocating driving motor torotate said field and armature simultaneously in opposite directions.

2. An electric generator embodying a field and an armature adapted to operate as flywheels, two crank shafts journaled in the same axial line'extended andcarrying said field and armature in operative-relations, and a cross-head provided with means for its reciprocation and pitmen connecting said cross-head and crank shafts.

3. An electric generator embodying a supporting frame; pillow-blocks for independent crank shafts to ,operate in a common axial line; a stationary cylinder arranged at right angles with these; guides in or parallel with the extended axis of said cylinder,
